Targeting pneumococcal vaccination to high-risk groups: a feasibility study in one general practice

The Department of Health recommends pneumococcal vaccination opportunistically or when immunising against influenza. This was a study in one general practice to assess the feasibility of targeting patients for pneumococcal vaccination in primary care. We also examined the rate of uptake of pneumococcal vaccine in identified risk groups after one year of a pneumococcal vaccination programme. A self-administered questionnaire was given to patients attending for influenza vaccine between September and December 1996. A total of 551/747 (73.8%) patients returned completed questionnaires. Few patients receiving influenza vaccination (133/509, 26%) were aware of pneumococcal vaccine. Only 55/108 (51%) of those given influenza vaccination were in a clinical risk group for pneumococcal vaccine. Attitudes towards vaccination were more positive and intention to take up pneumococcal vaccination significantly greater in high-risk patients compared to those who were not in a risk group. A targeted vaccination campaign directed at high-risk patients, bath opportunistically and those attending for influenza vaccination over one year, resulted in the following proportions of patients ia at-risk groups being vaccinated: coronary disease 144/312 (46%), diabetes 79/132 (60%), splenectomy 2/2 (100%), chronic obstructive airways disease and asthma 135/700 (19%), and chronic renal failure 5/9 (56%). Most doses of pneumococcal vaccine (336/463; 73%) were delivered to patients in high-risk groups. We conclude that a well-organised pneumococcal vaccination campaign can improve coverage of at-risk patients in general practice. Programmes to increase patient awareness of the vaccine, improved availability of vaccine, and practice guidelines, would help to target the vaccine to at-risk patients, Patients with chronic lung disease and asthma were particularly difficult to define and target in this study. A review of the UK guidelines, aligning those for pneumococcal and influenza vaccination and including patients over 65 years, would improve the logistics of vaccine delivery.
